Packaging solution with dust collection capability
productnews Cryogenic cross-flow filter dryer Suitable for both pharmaceutical and biotech processes, the cross-flow filter dryer from Power Systems Ltd (PSL) can be used in cryogenic operations down to -196 °C. The 0.05 m2 unit utilises a five-ply sintered mesh metal filtration plate, with a standard 20 micron pore size, as part of its conventional base filtration process. Other pore sizes can be custom-built upon request. According to the manufacturers, the wall section of the vessel has an additional profiled mesh that offers an effective cross flow filtration capability. The vessel walls and base are jacketed and lined with 25 mm of thermal insulation to ensure effective temperature control. Additional heating and cooling capacity is provided via a hollow shaft agitator, which is powered by a 0.28 kW air motor giving a maximum torque of 100 Nm at speeds of up to 25 rpm. The drying system has a filter cake capacity of 6 l and can only handle 12 l of liquid volume, so it is only suitable for small scale R&D, pilot scale production and clinical trials manufacturing in the pharmaceutical and biotech sector. Construction materials include 316 L stainless steel for the main body, agitator and shaft, with alloy 22 as an option for any areas likely to come into contact with product. The one-piece unit also has a fully welded design to avoid
Packaging solution with dust collection capability Tech Packaging LLC's new Series 2600 Bag/Pail dump station can add small amounts of dry material to manufacturing processes from either bags or pails. The system has an in-built mesh safety grate to remove any unwanted large particles from the process and can optionally be specified with a self-contained fan and filter assembly that is effective down to 1 micron. According to the manufacturers, the optional cloth filter is application specific and the 1 micron removal capability is its maximum performance capacity. Other materials can be specified where particulate removal does not have to be so precise. If the fan and filter assembly is not specified by the end user, the system is instead delivered with an external dust collection system. Construction materials for the main body of the system include carbon or stainless steel for more arduous batch metering applications. 12 December 2004
internal bolted joints, thereby eliminating the possibility of leaks or cross contamination. The entire assembly is built onto a central pivot shaft mounted onto a moveable stainless steel frame. This allows the vessel to be articulated through 180 °, which according to the manufacturers enables product discharge to be carried out via an in-built 100 mm nozzle. A double mechanical seal, with dry-run capabilities, provides rotational seal integrity claim the manufacturers. The lid is raised and lowered by a manual process involving a hand wheel.
Fine filtration with continuous automatic filter system The dynamic HydroFluid automatic filter system from Mann+Hummel offers filtration performance down to 10 microns in size for application in the process industries. It can be specified in standard 100 or 200 sizes with respective nominal flow rate capabilities of 15 m3/h and 30 m3/h at 0.15 bar of differential pressure. The maximum operating temperature is 110 °C and the standard construction material is stainless steel. Other materials are available upon request. The mains connection is 400 V AC, 50 Hz and the maximum permissible operating pressure is 6 bar. When in operation, dirty liquid flows tangentially into a ring channel located separately from the housing of the HydroFluid system. The ring channel design dampens the flow and provides pre-separation claim the manufacturers. Dynamic scrapers then move around the metallic filtering insert element without making contact. The dynamic scrapers, operating at a speed of 12 m/s, displace and rotate the liquid. Centrifugal forces transport the dirt particles away from the insert in the direction of the housing wall where they are continuously reflected downwards via a 10 micron gap. A partial vacuum is generated by the scrapers. According to the manufacturers this improves efficiency and prevents filter cake from forming on the surface of the insert, enabling continuous operation. Sludge discharge of the filtered material is regulated either by differential pressure or a time-controlled ejection system that can be specified with the control solution on the HydroFluid unit. According to the manufacturers, the dynamic contactfree operational mode of the HydroFluid system should ensure there is no loss of performance and provide end users with low maintenance requirements. www.filtsep.com
